Black-Hole Models in Loop Quantum Gravity [PDF]
Universe, 2020 Dynamical black-hole scenarios have been developed in loop quantum gravity in various ways, combining results from mini and midisuperspace models. In the past, the underlying geometry of space-time has often been expressed in terms of line elements with ...

A short review of loop quantum gravity [PDF]
Reports on Progress in Physics, 2021 AbstractAn outstanding open issue in our quest for physics beyond Einstein is the unification of general relativity (GR) and quantum physics. Loop quantum gravity (LQG) is a leading approach toward this goal. At its heart is the central lesson of GR: gravity is a manifestation of spacetime geometry.

Polytopes in all dimensional loop quantum gravity [PDF]
European Physical Journal C: Particles and Fields, 2022 The Lasserre’s reconstruction algorithm is extended to the D-polytopes with the construction of their shape space. Thus, the areas of d-skeletons $$(1\le d\le D)$$ ( 1 ≤ d ≤ D ) can be expressed as functions of the areas and normal bi-vectors of the (D-1)

Loop quantum gravity’s boundary maps [PDF]
Classical and Quantum Gravity, 2021 In canonical quantum gravity, the presence of spatial boundaries naturally leads to a boundary quantum states, representing quantum boundary conditions for the bulk fields. As a consequence, quantum states of the bulk geometry needs to be upgraded to wave-functions valued in the boundary Hilbert space: the bulk become quantum operator acting on ...

Quantum reduced loop gravity and the foundation of loop quantum cosmology [PDF]
International Journal of Modern Physics D, 2016 Quantum reduced loop gravity is a promising framework for linking loop quantum gravity and the effective semiclassical dynamics of loop quantum cosmology. We review its basic achievements and its main perspectives, outlining how it provides a quantum description of the Universe in terms of a cuboidal graph which constitutes the proper framework for ...

Particle Scattering in Loop Quantum Gravity [PDF]
Physical Review Letters, 2005 We devise a technique for defining and computing n-point functions in the context of a background-independent gravitational quantum field theory. We construct a tentative implementation of this technique in a perturbatively-finite loop/spinfoam model.

On gonihedric loops and quantum gravity [PDF]
Journal of Physics A: Mathematical and General, 2006 We present an analysis of the gonihedric loop model, a reformulation of the two dimensional gonihedric spin model, using two different techniques. First, the usual regular lattice statistical physics problem is mapped onto a height model and studied analytically.
